Everyone has at least one extra mouse laying around; why not get some use out of it? Disassembling the mouse you can get two optical encoders plus four infrared emitter/detector pairs. Then you can ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

Avago AEDT-981x is a family of industrial grade optical encoders offering from 2,000 to 5,000 counts per revolution (CPR) using a code wheel of 11mm optical radius. The devices are three channel ...

The C14 two-bit, panel-mount optical encoders are now available with optional IP65 protection against dust and water intrusion. The components allegedly deliver a very clean square wave output. They ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...

It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...
